The period after the Tropical Garden died out was a period of rapid development that led to the age of the dinosaurs similar to what happened on Planet Earth. The cooler dryer environment was at first inhospitable as it crept into the Tropical Garden. However, as the new environment gradually advanced there was a change and thinning out process. Those that could not adapt were at the end of the line and started to die out. Those that were able to adapt would move on and give rise to some of the great dinosaurs that inhabited the early planet.
During the period that the Tropical Garden flourished, there was a section in the garden that was populated by wild banana plants with small ponds inter-spaced in between them. As time passed, this became a rather unique ecosystem in and of itself. Tiny yellow fishes had became a fixture in this place. Later on yellow amphibians evolved out of this place as the tropical area died out and the lakes turned into a vast marsh. These yellow amphibians were the ancestors of a fearsome predator that arose that had tough, leathery skin with armor plating. An intense yellow in color as the result of a genetic mutation that worked in its favor, its pattern resembled that of a banana and was known as the Bananasauros. Unique to its kind, it had a prehensile tail that it could use to help trap and subdue its prey if necessary. As part of its adaptation to a cooler climate, the tough leathery skin had a layer of fat underneath as an adaptation to the cooler climate. Its distribution was uncertain but from the marshland of the former Tropical Garden, remains have been found in scattered caves in the form of fossilized eggs.
While the Tropical Garden was found in the temperate zone, there were other changes occurring on the Planet Gaus as well. Closer to the equator in the topics and subtropics there were other changes as well. A vast area of wetlands (i.e. swamps and marshes) had developed with plants that were adapted to growing in this environment and would feed on insects to make up for the lack of nutrients in the soil. One of them would be the ancestor of the infamous carnivorous plant of the Southern Bootheel.
